TOM SUTCLIFFE, OF LONDON, ENGLAND.

Application filed October 18, 1926,,Serial- No. 142,375, and in GreatBritain October 30, 1925.

The present invention relates to an improved closure or sealing cap forbottles, ars, and the like enclosures.

It has been usual to cover jars with a parchment cover tied with string.Certain metal caps have also been suggested in which the cap is securedby corrugations on a crimped gripping edge engaging under an upper heador the neck of the vessel the said gripping edge being cut away at twoparts to leave two smooth portions, directed obliquely outward, whilstone of the depending portions is provided with a tongue, also having oneor more corrugations extending through the lower upwardly bent edge ofthe tongue. A closure cap is also known having three tongues withinturned reentrant edges and a fourth tongue with an inturned hump aboveits lower edge.

The closure of the present invention comprises a cap having in one halfperiphery a depending inturned flange, the edge of which is in a planesubstantially parallel with the top surface of the cap and in the otherhalf periphery a tongue or tongues with an inturned hump above its loweredge, the inturned flange gripping under a corresponding flange on theneck of the jar whilst'the depending tongue lip or lips frictionallygrips the flange of the jar.

The closure is preferably nicked or slotted from its lower edge towardsits upper rim at points diametrically opposite to one another andlimiting the ends of the fully under turned semicircular edge.

The invention is more particularly de-- scribed with reference to theaccompanying drawings in which Figure 1 is a front elevation of one formof closure previous to its application to a jar.

Figure 2 is a corresponding side elevation. Figure 3 is an undersideplan view. Figure 4 is a front elevation of a modification.

Figure 5 is a corresponding side view. Figure 6 is a perspective view ofa closure mounted on a jar. 7 Figure 7 is a corresponding partialsectional elevation of the closure on the jar.

Figure 8 is a side elevation of a modified form of closure mounted onthe neck of a jar.

Figure 9 is a corresponding front view. The closure comprises a fiat topmetal cap 1 such as can be stamped from sheet metal having preferably adepressed central portion 2 thereby forming an internal recess 3 for thereception of an elastic rubber or the like a washer 4, which contactingwith the upper surface of the rim 5 on a jar 6 or the like enables ahermetic seal to be obtained.

The cap 1 has around substantially one half of its periphery a dependingedge or flange 7 the lower edge 8 of which is adapted to be turned underthe lowerflanged edge of the rim 5 of the jar to lie ina planesubstantially parallel to the plane of the top-of the cap. The ends ofthis under-turned flange portion 7 are preferably curved away as shownat 9, to leave a shallow rim portion 10 which does not extend under thetop rim of the ar.

In the other half periphery of the cap and on the opposite side to thedepending underturned rim 8 are arranged a pair ofv tongues 11, 12having an inturned hump, 19 forming a frictional grip engaging the rim 5of the jar. These tongues 11, 12 may be separated by a narrow slot 13,01they may be in the form of v one tongue 14: connected with the under--turned edge 8 by a sloping surface 15, as shown for instance in Figures4:, 5 and 6. Previous to application of the closure to the jar, it wouldpreferably be in the form shown in Figures 1 and 2, the depending rim 8and the lips 11, 12 being turned under when this has been applied to thejar, but it will be obvious that the closure can have the form shown inFigures 6 to 9 previous to application to the jar.

In the modified construction of Figures4, 5, 6 and 7,the cap 1 isprovided with an underturned flanged edge 8 as before, but this is'eX-tended as shown at 16 for a short distance, but as the sloping surface15 is passing upwards to meet the tongue 14- a notch or cut 17 isprovided between the parts 8 and 16 so that a virtually elastic springhinge is formedacross the jar, as indicated in dotted lines 18.

In use after the jar has been scaled, and it is desired to obtain accessto the contents, the tongue 14 due to its frictional engagement with theflange on the jar, can be lifted away from the under-cut rim 5by thefinger or by a blunt tool, such for instance, as the edge of a coin,when it will be found that the cap will hinge somewhat in twosemicircular parts and the closure can be easily removed from the jar,whilst atthe same time permitting it to be snapped back on the jar inview of the elasticity of the parts toobt-ain the i8 and 9, the closurehas a rim 8 extending under the flange 5 of the jar as previously, andis provided with a single humped tongue 24: on the opposite side anddepending lip 20 for facilitating its removal. In this form of closureit will be found that by turning up the lip 20, the closure can bereadily removed by first lifting up one side of the closure by means ofthe tongue 24 and then sliding the closure away in the direction of thearrow 21, this being assisted by the virtual hinging of the two partsdue to the notch 22.

The construction according to the present invention provides a cheapclosure which will give a hermetic seal of-the jar and yet also providemeans whereby the jar can be rescaled during use of the contents.

The closure of the present invention as will be seen, is directlyapplicable to the existing standard pattern of jam jars having a groove23 at the neck. 1

I declare that what I claim is 1. A closure for receptacles comprising apair of half caps united but elastically hinged together, a dependingflange on one half cap, an inturned edge substantially parallel withthetop surface of the cap on said depending flange, and a hump tongue onthe other half cap,

2. A closure for receptacles comprising a cap adapted for ficxure acrossa diameter, a depending flange on one half perpihery of said cap theedge of which is under-turned to lie in a plane substantially parallelto the top of the cap and a depending tongue alone on the other halfperiphery having an inturned hump above itslower edge.

3. A closure for receptacles comprising a cap adapted for flexure acrossa diameter, a

hooked flange on one half periphery of said cap adapted to engage overand under a flange on the neck of the receptacle and a frictionallyengaging tongue on the'other half periphery engaging the flange on thereceptacle.

4. A closure for receptacles comprising a cap adapted for fleXure acrossa diameter, a depending underturned flange on one half periphery of saidcap'forming a positive lock and a snap *atch on the other half peripheryforming a friction lock.

5. A closure for receptacles comprising a 'cap adapted for flexureacross a diameter, a

depending flange on one half periphery of said cap terminating at theends of said diameter, an edge on said depending flange underturned tolie in a plane substantially parallel to the top of the cap and adepending tongue alone on the other half periphery having an inturnedhump above its lower edge.

6. A closure for receptacles comprising a cap adapted for flexure acrossa diameter, a hooked flange on one half periphery of said capterminating at the ends of said diameter and adapted to engage over andunder a flange on the neck of the receptacle and a frictionally engagingtongue on the other half periphery engaging the flange on thereceptacle.

7. A closure for receptacles comprising a cap adapted for fleXureacrossa diameter, a depending underturned flange on one half peripheryof said cap tern'iinating at the ends of said diameter forming apositive lock and a snap catch on the other half peripheryforming afriction lock.

8. A closure for receptacles comprisingai cap, a run on said cap havingup cut notches at substantially diametrically opposedipoints I and anoperating upturned lip on the lower end of said tongue, the halfperipheries-being bounded by up out notches in said rim which serve toweaken said capwhereby itis adapted for flexure across a diameterdefined by said notches.

10. A closure for receptacles comprising a cap, a depending flange ofuniform depthon one half periphery of said cap, an edge on said flangeunderturned to lie in aplane substantially parallel to the top :of thecap, a depending flange onthe other half-periphery of depth varyinginversely as the peripheral distance from the ends of said flange ofuniform depth to leave upcut notches :at the junctions of said flangesand a depending tongue located on" said flange of varying depthequidistantly fromsaid notches, said tongue having an inturned humpaboveits lower edge.

11. A closure for receptacles comprising a cap, a hooked flange on onehalf periphery of said cap adapted to engage over and under a flange onthe neck of the receptacle, adepending flange on the other halfperiphery oi depth varying inversely as the peripheral distance from theends of said hooked flange to leave upcut notches at the junctions ofsaid flanges and a frictionally engaging tongue on said depending flangelocated equidistantly from said notches, said tongue being adapted toengage the flange on the receptacle.

In witness whereof, I have hereunto signed my name this 6th day ofOctober, 1926.
